The inspection of storage tank bottom is a costly endeavor with current technologies. In order to perform the**inspection, the tank currently needs to be emptied and scanned using a magnetic-flux leakage scanning system.**The main drawbacks of the current method is the cost associated with emptying the tank and the cost of the**equipment and training required. This project will investigate the feasibility of using ultrasonic guided waves**for thickness mapping from a transduction position on the annular chime of the tank. Two methods will be**evaluated: (1) high order mode cluster and (2) high order shear horizontal wave structural filtering.

储罐底部的检测是一项成本高昂的奋进，采用当前的技术。为了进行 ** 检查，目前需要清空储罐并使用漏磁扫描系统进行扫描。目前的方法的主要缺点是与清空油罐有关的费用以及所需的设备和培训费用。该项目将研究使用超声导波 ** 从储罐环形凸边上的换能位置进行厚度映射的可行性。将 ** 评估两种方法：（1）高阶模式簇和（2）高阶剪切水平波结构滤波。
